基于CIE标准色度观测器，即独立于设备的色彩空间，相机输出的RGB信号并不直接对应于三色刺激值。研究了基于多项式回归模型的数码相机色度表征。通过改变多项式系数矩阵和训练样本数的实验对表征性能进行了评价，较好的多项式矩阵为11×3，再现颜色与目标颜色之间的平均色差为2.874ΔEAB，具有普遍应用价值。
The camera output RGB signals do not directly corresponded to the tristimulus values based on the CIE standard colorimetric observer,i.e.,a device-independent color space.In this paper,digital camera colorimetric characterization based on the polynomial regression model was studied.The characterization performance was evaluated by experiment of varying coefficient matrix of polynomials and the number of training samples.The better polynomial matrix is 11×3,and the mean color difference between the reproduced colors and target colors is 2.874ΔEab,which can be applied in common application.
